Hi all, I'm curious who has or has tried the Aevit joystick driving system (the one where steering, braking, gas are all controlled within a joystick)? How much different is it then operating a joystick on a motorized chair (beside the obvious difference of speed, weight, risks, etc.)? Can the sensitivity be adjusted much like the controller on a wheelchair can, so that every little movement does not cause a response? And how reliable are such systems? Thanks!
